Not really, conventional bank is haram in Islam, but if the bank is using Islamic name e.g. sharia and then they claimed to not offering interest rate, actually it's legal. Do you want to say Sharia bank is haram? you will get mocked and bullied by Muslims 
Haram is haram. There is no other excuse. Taking interest in return for the money lent is not allowed. No matter what Sharia bank or Islami bank calls it. Most of them call it as service charge, or whatever, it's haram. I am Muslim myself and I know it's Haram. If some bullies me because of that, I will take that. In case they can teach me something new.
If someone open a bar a of vodka in the name of Islam, it won't become halam vodka. If people say Bismillah before they drink vodka, it won't become a halal drink. Real practicing Muslims won't debate regarding these things. They will say I said what I had to. No need to spread Fitna.
